摘　　要：本文从矿床的地质评价入手 ,对矿体形态、产状、规模 ,矿石的物质成分 ,矿石结构构造 ,铀的存在形式 ,矿床水文地质、工程地质等诸多方面进行了矿床溶浸天然地质条件研究 ;通过对低品位、大块度的铀矿石进行柱浸工艺试验 ,获得了一系列溶浸工艺参数 ;归纳分析出高昔、牛尾岭矿床的矿石为第2类有利溶浸类型 ;提出常规采冶法、原地破碎浸出和堆浸相结合的采冶方案。Based on the geologic assessment of the uranium deposit, the form, occurrence and size of the ore bodies, the composition, texture and structure of the uranium ore, the existing form of uranium, the hydrogeology and engineering geology of the deposit are studied in terms of natural geologic conditions for solution leaching of the deposit. Having tested the low grade big lump uranium ore by column leaching technology, a series of technological parameters of solution leaching are obtained. It is concluded, that ores of Gaoxi and Niu weiling uranium deposits belong to the second favorable type for solution leaching. Then, a mining hydrome tallurgical project of combining traditional mining hydrometallurgy, in place fracturing leaching and heap leaching is proposed.
